Philips ECG XML Information
The PageWriter TC cardiographs export ECG data in XML (Extensible Markup Language)
format. There are three available XML schema versions on the cardiograph: version 1.03,
version 1.04, and version 1.04.01. Version 1.03 exports ECG data in 12-lead format only,
version 1.04 exports ECG data for up to 16 leads, and version 1.04.01 exports ECG data for up
to 16 leads and includes full interpretation from the Philips DXL ECG Algorithm.
Information regarding the Philips ECG XML schema can be obtained directly from Philips
Medical Systems by sending an email request to: ecg@philips.com. Please include your
name, facility, and the serial number of your PageWriter TC cardiograph in the email request.
NOTE
The default XML version setting on the cardiograph must be coordinated with the XML version
compatibility of the TraceMaster ECG Management System, or other third party ECG management
system used by your facility. For more information on configuring your cardiograph for use with an
external ECG management system, see the PageWriter TC Network Configuration Guide included on the
User Documentation and Training DVD, or download the file from the Philips InCenter site.

Battery Maintenance and Care
Cardiograph Care and Maintenance
Battery Maintenance and Care
The PageWriter TC70 cardiograph operates with two removable lithium ion batteries that
supply power to the cardiograph during mobile use. The PageWriter TC50 and PageWriter
TC30 cardiograph use either one or two removable lithium ion batteries that supply power to
the cardiograph during mobile use.
For optimal battery performance:

When operating the PageWriter TC50 or PageWriter TC30 cardiograph with one battery
installed, only use the Philips battery with part number 989803170371. Do not use the
battery with Philips part number 989803160981 for one battery operation.

When operating any model of the PageWriter TC cardiograph with two batteries installed,
ensure that both batteries contain the same Philips part number. The battery part number
identification label is found on the bottom of the battery. The cardiograph cannot operate
with two batteries that contain different part numbers. If the cardiograph is operated with
two batteries with different part numbers, the cardiograph will display an error message.
Before initial use, fully charge the batteries for five hours before operating the cardiograph
without AC power. Regularly and consistently charging the batteries will prolong battery
life.

Charging, storing, or using the batteries at temperatures above 50 oC (122o F) can damage
the batteries and reduce overall battery life.

Check the battery power indicator on the Status Bar. Tap the battery icon on the Status Bar
for information on remaining battery power, see Figure 1-18 on page 1-39.

Always charge the batteries when the cardiograph is not in use. Plug the cardiograph into
AC power. Ensure that the green AC power indicator light on the front of the cardiograph
is lit. The batteries will charge while the cardiograph is in use, but will charge at a slower
rate.

Operate the cardiograph, charge the batteries, and store the batteries at a room temperature
of 25 oC (77o F) or lower. Exposure to higher temperatures may reduce battery life,
damage the batteries, and degrade overall cardiograph performance.

If the cardiograph will be stored for more than sixty days without use, fully charge the
batteries, and after the batteries are fully charged remove AC power from the cardiograph,
and then remove the batteries from the cardiograph. Store the batteries in a cool, dry
location. A set of fully charged batteries stored outside the cardiograph will need to be
recharged every sixty days.

Cardiograph Overall Sensitivity Test
The overall sensitivity test is used to test the calibration voltage. According to
IEC 60601-2-51, this test should be run regularly. Taking an ECG using a 12-lead simulator
allows you to verify areas of operation that the extended self tests cannot check, and allows
you to verify the accuracy of the sensitivity settings. This test should be run approximately
once a year.
Before You Begin
To perform this test, you need an ECG simulator that is calibrated and is able to produce a 1mV
2 Hz square wave on Lead I or II. (The lead you use is dependent on the simulator.)
Performing the Sensitivity Test
To perform the test:
1
Set the simulator to the 2Hz square wave setting and the amplitude to 1mV.
2
Ensure that the Simulated Waveform feature (cardiograph displays simulated patient ECG
waveforms) is not enabled on the cardiograph.
3
Touch the Exam button on the Status Bar, and then touch the Resting 12-Lead button.
4
Touch the factory default Standard 12-lead Exam Profile button.

Touch the Settings button on the Status Bar.
a
Set the Artifact filter to OFF.
b
Set the Limb Leads setting to 10 mm/mV.
c
Set the Speed setting to 25 mm/sec.
d
Touch OK.
6
Touch the ECG button on the toolbar. If a message appears that no patient information has
been entered, touch the Continue button. Depending on how the cardiograph is
configured, the ECG may automatically print. If not, touch the Print button.
7
Verify Lead I or II for the following items on the printed report:
–
The height of the ECG pulses for the sensitivity setting
–
Measure the peak of the ECG pulse and calculate the voltage for the sensitivity setting
–
Verify that the measured voltage value is 1mV. Count the boxes that are contained in
the square wave from the top to the bottom, using the top left corner of the square
wave labeled A in Figure 2-8 as the upper boundary, and the lower right corner of the
PageWriter TC Cardiograph Service Manual
2-19

Troubleshooting Cardiograph Issues
Troubleshooting
Signal Acquisition Issues
Before attempting to troubleshoot a signal acquisition error as a mechanical issue, ensure that
the following patient preparation and basic troubleshooting techniques have first been
followed.
Always follow good skin and patient preparation techniques prior to taking an ECG. Proper
skin preparation helps to ensure a good quality ECG. Skin is a poor conductor of electricity
and frequently creates artifact that distorts the ECG signal.
To prepare the patient for an ECG:
1
Shave hair from electrode sites if necessary (excessive hair prevents a good connection).
2
Wash the skin thoroughly with soap and water.
3
Dry the skin vigorously to increase capillary blood flow to the tissues and to remove the
dead, dry skin cells and oil.
NOTE
Do not use alcohol to clean the skin because it dries the skin. If there is no time, rub the
electrode sites with gauze to remove the dead, dry skin and to increase capillary flow.
4
Always use disposable electrodes, and ensure that the disposable electrodes have not
expired. Place the electrodes on flat, fleshy parts of the arms and legs, and place all limb
electrodes equal distance from the heart, at the same position on each limb. If a limb site is
not available (amputation, injury) place the electrodes closer to the torso.
5
Ensure that all electrodes are firmly attached, and that the lead wires are not pulling on the
electrodes. If the electrodes can be moved easily, the electrode connection is too loose.
6
Reassure the patient and make sure that the patient is comfortable. If the patient has
tremors, attach the limb electrodes higher on the patient (closer to the torso), and assist
with limiting patient moving while taking the ECG.
After ensuring that proper patient preparation techniques are being followed, and that fresh
electrodes are being applied to the patient, review the following table for further assistance.

2
Ensure that a Class B PIM is connected to the
cardiograph. See “About Class A and Class B
Patient Data Cables and PIMs” on page 1-27.
3
If the PIM is firmly attached, perform the PIM test
as described in “Patient Interface Module (PIM)
Test” on page 2-14. If the PIM Test fails, replace
the patient data cable. If the PIM Test continues to
fail with a new patient data cable attached, replace
the PIM.
4
If the PIM test passes, ensure that all lead wires are
fully seated in the PIM lead connectors.
5
Ensure that all lead wires are intact and that there
are no cracks visible in any of the lead wires.
6
Run the Lead Wire test, see “Lead Wire
Performance Test” on page 2-15. Replace any
defective lead wires.

electrodes
1
Ensure that the lead adapters are clean and have a
tight fit.
2
Ensure that the electrodes are within their shelf life
and are firmly attached to the patient.
Defib or high noise
event
1
Observe frequency and recovery behavior.
2
The PIM performs an automatic ranging action
when input signals vary significantly. If this
behavior persists in the absence of electrode
movement or defib events, the cardiograph should
be serviced to inspect and possibly replace the PIM
or lead cables. Contact the Philips Response
Center for assistance, see “Contacting a Philips
Response Center” on page 5-13.

Viewing and Saving Log Files
Viewing and Saving Log Files
All test results are entered in the Event Log that is displayed on the screen. Additionally, you
can save all log files to a USB memory stick using the Save Logs feature in Setup, or use the
key command Ctrl + Alt + O from any screen. Ensure that a USB memory stick is firmly
connected to the cardiograph before saving log files. Also, the cardiograph can be configured
to automatically or manually transmit log files directly to a specified TraceMaster ECG
Management System server, or to any other networked computer or server that is accessible
over a LAN or WLAN. For more information on configuring and using a remote server to
receive log files, see the PageWriter TC Cardiograph Network Configuration Guide.
About Log Files
Log files continuously record operating information about the cardiograph including events,
errors, application integrity, battery power levels, memory use, test results, and user events
related to ECG processing, along with the time and date of each event.
Figure 3-21 shows the Event Log as it appears on the Diagnostic Tests and Utilities screen.

Saving Log Files
The following log files can be saved to a USB memory stick, or can be transferred to a
specified remote server:

system1.log

system2.log

CFG.xml
These log files are useful in troubleshooting cardiograph issues.
When exported from the cardiograph, the log files are saved to a syslog directory. Within the
syslog directory, the two system log files are found. The file system1.log contains the most
recent event log information, and can reach a maximum size of 2 MB. Once the system1.log
file reaches 2 MB, the data in this file is moved to the system2.log file. The system2.log file
retains this saved event log information until it is replaced again by more current information
being moved from the system1.log file.
If the cardiograph is configured to automatically transfer log files and configuration files to a
remote server, the syslog directory will also contain an AutoSave folder. This folder contains
files that are scheduled for automatic transmission to a remote server. The files contained in
this folder may or may not be as current as the files saved to the syslog directory; this is
dependent upon on when the last automatic transmission to a remote server occurred.
Figure 3-22
NOTE
The Syslog directory
A DumpFiles directory may appear at the same level as the syslog directory. The DumpFiles
directory contains error information that can be used by Philips personnel for troubleshooting

Required Testing Levels
The Performance Verification Tests verify proper operation of the PageWriter TC cardiograph
following a service event. The level of testing required corresponds to the type of service
performed.
NOTE
Installation and Preventive Maintenance are not considered service events since the cardiograph is
designed to be installed and maintained by the user. Service Events are divided into two categories:
Repairs and Upgrades. Repairs are then further divided into External Repairs and Internal Repairs.
External Repairs
External Repairs consist of repairs or replacements of one or more items. Repair or
replacement of these items does not require you to open the cardiograph case, therefore only a
limited number of tests are necessary to verify performance post-repair. External repairs that
involve the PIM, PIM data cable, and PIM lead set require an ECG simulation test to verify
proper ECG signal path.
The typical external repairs include:

PIM


Batteries

Paper Tray

AC Power Cord


Internal Repairs
Refer to Table 4-18 for the required test blocks that must be performed after any external
repair occurs.
Internal Repairs
If the case was opened, regardless of the repair, you must perform additional Performance
Verification Tests. Refer to Table 4-18 for the required test blocks that must be performed
after any internal repair.
Upgrades
NOTE
There are no upgrades available for the PageWriter TC70 cardiograph.
Most PageWriter TC50 cardiograph and PageWriter TC30 cardiograph upgrades are installed
by the user, and are not considered service events. The only exceptions are upgrades for the
software and the magnetic card reader. Refer to Table 4-18 for the required test blocks that
must performed after these upgrades.

PIM Test (PIM)
This test is used to confirm that the Patient Interface Module (PIM) is communicating with the
cardiograph. This test can be performed when the cardiograph displays PIM error messages, or
when the cardiograph is unable to acquire data from the PIM. Be sure that the PIM patient data
cable is securely attached to the PIM connector on the rear of the cardiograph before
performing the test.
If this test fails, it may indicate a problem with the PIM or with the PIM patient data cable.

ECG Simulation (ECG)
Taking an ECG using a 12-lead ECG simulator allows you to verify areas of operation that the
extended self-test cannot check:

Integrity of the patient leads

Accuracy of the paper speed (not available on all simulators)

Accuracy of the gain settings (not available on all simulators)
The recorded ECG trace should look similar to the one shown in the following figure. Trace
differences may result from differences in simulators, simulators settings, and from
differences in configuration and control settings on the cardiograph.
Figure 4-29
Simulated 12-Lead ECG
To make a simulated ECG recording
1
Connect the PIM lead wires to the simulator.
Verify that all lead wires are connected by observing the display for flat lines.
2
Touch the Map button on the Toolbar.
Check the leads map to be sure that a red x
does not appear next to any electrodes.
3
Firmly pull each lead wire tight, and then look for excessive noise on the display (may be
indicated by yellow or orange waveforms).
4
Touch the ECG button on the toolbar. If a message appears that no patient information has
been entered, touch the Continue button.
Depending on how the cardiograph is configured, the ECG may automatically print. If not,
touch the Print button.

NOTES
Performance Verification Tests
Verify the following items when printing is complete:
–
Trace activity for all leads. Confirms integrity for all patient electrodes and leadwires.
Noise should measure less than one (1) mm, with no baseline wander.
–
No gross distortion of complexes or calibration pulses (no overshoot and so forth).
–
Duration for calibration pulses for correct paper speed. With cardiograph set to record
at 25 mm/sec, the calibration pulse should measure 5mm (calibration pulse duration is
200 ms).
–
Calibration pulse amplitude is correct.

An arrhythmia simulator is not an acceptable tool for verifying computerized ECG analysis. The
analysis software is biased to process human ECG data.

Noise may be an artifact of poor connections to the simulator or position of the cables. If noise
appears, check the connectors or adjust the cable drape.
Safety Tests
This section covers tests of the cardiograph’s electrical safety.
NOTE
The PageWriter TC70 cardiograph is an electrical Class II device in which the protection against
electrical shock does not rely on basic insulation and a protective earth conductor, but on double and
reinforced insulation.
Test Notes

Use the procedures called out by the manufacturer of the safety analyzer in use.

Test both Normal and Reverse polarity line connections for each test, and record the
worst-case value.

Use the barrel of the PIM connector to connect a test lead to chassis bare metal for the
leakage tests.

Special Note about Welsh Bulb Electrodes
Figure 5-5
Welsh Bulb Electrode
Welsh Bulb electrodes are offered as an optional supply part with the PageWriter TC
cardiograph. Special care is necessary when using these electrodes. Pay special attention to all
warnings associated with these electrodes. For information on cleaning the reusable Welsh
Bulb electrodes, see “Reusable Electrode Cleaning" on page 3-4. Philips Medical Systems
recommends the use of disposable electrodes with the PageWriter TC cardiograph.
WARNING
The Welsh bulb electrodes (available as an accessory for the cardiograph) do not meet
the requirements of IEC 60601-2-25 for defibrillation recovery time, and cannot be
reliably used for patient diagnosis immediately following defibrillation.
WARNING
Always clean and disinfect reusable electrodes before patient use. See “Reusable
Electrode Cleaning” on page 3-4 for information on cleaning and disinfecting reusable
electrodes. Failure to properly clean and disinfect reusable electrodes before patient use
may cause infectious materials to be transferred between patients.
CAUTION
The Welsh bulb electrodes contain natural rubber latex which may cause allergic reactions.

Theory of Operation
Overview
Overview
At a system level, the PageWriter TC cardiograph performs acquisition, analysis, printing,
storage, and transfer of ECG waveforms and other patient clinical data.
The PageWriter TC cardiograph consists of three major subsystems:

Main board
A main control board built around a powerful embedded processor (Marvell PXA270)
with extensive I/O facilities, running Windows CE 5.0. The PageWriter TC cardiograph
software application runs on the main board, which supports the display and user-input
subsystems.

Print controller
A FPGA-based (Altera Cyclone-I) control circuit, embedded in the main board that
provides all the real-time management of the printer.

Patient Interface Module (PIM)
An embedded processor (Marvell PXA270) running Windows CE 5.0, coupled with a
signal acquisition board employing Philips proprietary mixed-signal ASIC technology for
ECG acquisition. The PIM communicates with the main board through USB.
Hardware Logical View
Control of the PageWriter TC cardiograph is provided by application software running on the
main board, interacting with numerous hardware and software subsystems. The following are
high-level descriptions of these various subsystems.
Main Board
The main board contains loader software and the Windows CE kernel image in its internal
flash memory (64 MB).
At system boot, a basic interface configuration is performed by the loader and then the
Windows CE kernel loads. When Windows CE loads, the application launcher runs, verifying
system and executable images before loading the main application. All interaction with the
user is through the Athena_APP application. This application software is stored in internal
Flash memory.
Figure 8-1 illustrates the devices and interfaces provided by the main control board.

Devices and Interfaces for the Main Control Board
The main control board (together with interface boards and cables) allows the user to access
interfaces including Compact Flash wireless LAN, USB connector, the PS/2 connection for a
barcode reader device, the phone connector for a modem, and an RJ45 connector for LAN.

Theory of Operation
Hardware Logical View
Display
The PageWriter TC70 cardiograph display is 1024 x 768 pixels, up to 65536-color TFT LCD
with backlight. All display functions are handled by the main control board using the CPU
LCD port.
The PageWriter TC50 cardiograph display is 800 x 600 pixels, up to 65536-color TFT LCD
with backlight. All display functions are handled by the main control board using the CPU
LCD port.
The PageWriter TC30 cardiograph display is 640 x 480 pixels, up to 65536-color TFT LCD
with backlight. All display functions are handled by the main control board using the CPU
LCD port.
Patient Interface Module (PIM)
The PIM is a PXA270-based WinCE subsystem that is connected by the USB to the main
control board. It provides real-time data acquisition of ECG signals from electrodes connected
to the patient.
Printer Control (FPGA)
All data printing is handled by the main control board. The printer control is an Altera
FPGA-based control circuit. It accepts printable data, provides basic bitmap imaging
operations, and controls the printer head and motor.
Battery (Lithium Ion)
The PageWriter TC70 cardiograph only operates with two batteries installed. The PageWriter
TC50 and TC30 cardiographs can operate with either one or two batteries installed with
software version A.04.00 and higher. Each battery is a lithium ion, 11.1-volt, providing 7.2
amp-hours of current when fully charged.
NOTES

When operating the PageWriter TC50/TC30 cardiograph with one battery installed, only use the
Philips battery with part number 989803170371. Do not use the battery with Philips part number
989803160981 for one battery operation.

When operating the PageWriter TC50/TC30 cardiograph with two batteries installed, ensure that
both batteries contain the same Philips part number. The battery part number identification label
is found on the bottom of the battery. The cardiograph cannot operate with two batteries that
contain different part numbers. If the cardiograph is operated with two batteries with different
part numbers, the cardiograph will display an error message and will not operate.
Keyboard and Buttons
The PageWriter TC cardiograph includes a laptop-format, PS/2, sealed, full-key action
keyboard. Also included are three function buttons, used to turn the cardiograph on and off, for
patient ID input, and ECG capture. These three function buttons are designed to support the 12-3 ECG capture operation, and also have LED backlights to illustrate their current status.
The keyboard function includes a keyboard matrix, a PS/2 encoding chip on an interface
board, and is managed through standard Win CE device drivers.

CAUTION
Only use the USB memory stick to transfer data between the cardiograph and a computer. Do not use
the USB memory stick with other devices.
Wireless LAN Card
A wireless LAN Card is available as an option for the PageWriter TC cardiograph. The LAN
card connects to the cardiograph through the Wireless LAN card slot and provides standard
WLAN capability. The PageWriter TC cardiograph communicates with the TraceMaster ECG
Management System, networked PC or server, or other third party ECG management system.
Modem Module
A modem module is available as an option for the PageWriter TC cardiograph. The modem is
installed on the I/O module and interfaces to the main board through an RS232 connection,
providing standard modem capability. The PageWriter TC cardiograph faxes ECG data to
remote receivers or communicates with a TraceMaster ECG Management System, or other
third party ECG management system through the modem module.
WARNING
Do not connect the modem card to a phone line when the cardiograph is connected to a
patient.
High Level ECG Data Flow and Storage
General ECG data flow begins with acquisition by the Patient Interface Module (PIM) from
electrodes placed on a patient. Data is streamed real-time to the main control board, where it is
received into the application buffers in RAM. These buffers are used to present the signal data
on the real-time screen. When the user initiates an Auto ECG print, the corresponding
10-second segments of the signal data are then copied to the temporary ECG storage memory
in RAM.
These 10-second segments are named ECG reports that can be previewed and printed. In the
case of Auto mode, the ECG report may be configured to automatically print. An ECG report
contains signal data, analysis information, patient demographics, and acquisition information,
along with operator and device information. For information on the Philips ECG XML
schema, see “Philips ECG XML Information” on page 1-3.
If the Save button on the cardiograph is set to Auto, the ECG report is saved in XML format to
the internal main archive. This archive is non-volatile and resides on the internal
8-6
PageWriter TC Cardiograph Service Manual
High Level ECG Data Flow and Storage
Theory of Operation
CompactFlash (CF) card. An index file with a CDB extension is also maintained in this
archive.
From the internal main archive, the ECG XML data format files can be copied, deleted,
previewed, printed, and transferred to other devices. The internal main archive cannot receive
ECG XML files from external devices. Retrieved ECG file storage is limited to the internal
remote archive.
NOTE
PageWriter TC cardiograph-generated ECG XML files comply with the Philips Medical Systems ECG
XML Schema version. They incorporate an embedded CRC32 value, which is used to ensure the data
integrity of the file.

Internal Main Archive
The internal main archive resides on the internal CompactFlash (CF) card, and is used as the
primary ECG data repository. This archive is referred to as the Main Archive in the software
application. ECG XML files, and a related index file are stored here in the
PhilipsArchiveInternal directory. All stored ECG files transition through this archive prior to
transfer or copying to other devices, such as the USB memory stick.
Currently, the internal main archive is limited to storing 200 ECGs.
Internal Remote Archive
The internal remote archive resides on the internal CompactFlash (CF) card much like the
internal main archive. All XML files retrieved from remote sites, such as the TraceMasterVue
ECG Management System, reside in this archive until deleted. ECG XML files and related
index files are stored in the PhilipsArchiveRemote directory.
Currently, the internal remote archive is limited to a maximum of 100 ECGs.
External USB Memory Stick Archives
The external USB memory stick archives reside on a compatible memory stick connected to
the USB port. Files can then be transferred to a connected memory stick using the Archive
feature of the application software, and are stored in XML format. A CDB file is created and
maintained on each compatible USB memory stick when ECG files are transferred to the USB
memory stick. Currently, a USB memory stick archive is limited to storing 200 ECGs.
NOTES
The PageWriter TC cardiograph only supports the USB memory stick that is shipped with the
cardiograph, or that is available for purchase as an optional accessory from Philips Medical Systems.
Philips does not guarantee that other USB memory sticks are compatible with the PageWriter TC
cardiograph.
When you add or delete compatible ECG XML files from a memory stick (not using the cardiograph),
it is recommended that you delete all CDB files prior to reconnecting the memory stick to the
cardiograph. In the absence of a CDB file, the cardiograph automatically regenerates the index based
on the XML files on the memory stick.
Rendered ECG Report Prints
A rendered ECG report print is a hard copy representation of the ECG data. This includes a
high-resolution print of the signal data, and may include configured patient demographics,
acquisition information, and other non-signal data elements.
The PageWriter TC cardiograph allows the user to customize the fields on an ECG report
print. The report print may consist of one or more continuous pages on perforated thermal
media from the printer.

Fax-Rendered ECG Report Print
A fax-rendered ECG report print is equivalent to the rendered ECG report print, as described
in the previous section, except it has been adjusted to comply with fax transmission and
resolution device requirements. When the user starts a fax transfer, the ECG report is rendered
and transmitted to a remote receiving fax machine that has been pre-configured on the
cardiograph, using the optional fax and modem. The fax-rendered ECG report print may be
stored on the received system end as an electronic file, and not actually used to produce a
printed copy.
NOTE
WARNING
8-10
No guarantee is made as to the suitability of the faxed ECG for any particular purpose, due to the
variability inherent in fax technology.
Do not connect the modem card to a phone line when the cardiograph is connected to a
patient.
PageWriter TC Cardiograph Service Manual
Power System Overview
Theory of Operation
Power System Overview
The PageWriter TC cardiograph power system consists of:

One 60-watt AC/DC medical grade power module

One or two 11.1 volt, 7.2amp-hour lithium ion rechargeable batteries

Battery charging circuitry, various voltage regulators, and logic circuitry on the main
board
The PageWriter TC cardiograph is designed to run on AC power or battery power. The main
board contains a battery charging chip that controls battery charging. The main board has an
A/D converter that monitors the voltage of the power supply, and a smart battery controller
(part of the charging chip) that monitors the battery charging status.
The major power draws within the PageWriter TC cardiograph is the LCD display backlights,
which can draw up to 19 watts, and the thermal printer, which can draw approximately 35
watts. Provisions have been incorporated into the PageWriter TC cardiograph that allows the
user to adjust the display brightness. To extend battery life, set the display brightness to the
low or medium setting. Also, activate the power save mode (entering standby) to further
extend battery life. The printer control circuitry is current-limited for normal printing.
However, if print demand is too high, the current limiter will not print the output, resulting in a
faded page.
Battery
The one or two 11.1V rechargable lithium ion batteries provide power to the PageWriter TC
cardiograph, and can support full cardiograph functionality without AC when properly
charged. Built-in protection circuitry in each pack prevents damage to the battery by
overcharging, over discharging, over current, and over temperature.

responsibility of the operator to comply with IEC 60601-1-1 and test the medical system
according to the requirements. For additional information contact Philips Medical
Systems.
Electromagnetic Compatibility (EMC)
Electronic devices can either generate or receive electromagnetic interference. The PageWriter
TC70/TC50/TC30 cardiograph have been evaluated for electromagnetic compatibility (EMC)
with the appropriate accessories according to Medical Collateral standard IEC 60601-1-2,
Edition 2 (with exceptions noted in proceeding tables). This IEC standard has been adopted in
the European Union as the European Norm, EN 60601-1-2, Edition 2.
WARNING Radio frequency (RF) interference from nearby transmitting devices may degrade
performance of the electronic equipment. Electromagnetic compatibility with
surrounding devices should be assessed prior to using the equipment.
WARNING Fixed, portable, and mobile radio frequency communications equipment can also affect
the performance of electrical equipment. See your Service Provider for assistance with
the minimum recommended separation distance between RF communications
equipment and the PageWriter TC cardiograph.
WARNING The use of accessories and cables other than those specified in the Philips PageWriter
TC cardiograph service and user documentation can result in increased emissions or
decreased immunity of the system.
WARNING The PageWriter TC cardiograph should not be used next to or stacked on top of other
equipment. If you must stack the product, you must check that normal operation is
possible in the necessary configuration before the product is used.
Reducing Electromagnetic Interference

Specifications
Electromagnetic Compatibility (EMC)
other medical devices, wireless devices, information technology equipment, and radio/
television transmission. Should interference be encountered, as demonstrated by artifact on the
ECG trace, unintended change on operating state, or unit lockup, attempt to locate the source
by assessing:

if the interference is intermittent or constant?

does the interference occur only in certain locations?

does the interference occur only when in close proximity to certain medical devices?

does the ECG signal quality change dramatically when the AC power cord is unplugged?
Once the source of the interference is located, attempt to attenuate the EMC coupling path by
distancing the cardiograph from the source of the interference as much as possible. If further
assistance is needed, contact the Philips Response Center nearest you.

Electromagnetic Compatibility (EMC)
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the PageWriter TC
cardiograph are used exceeds the applicable RF compliance level above, the PageWriter TC cardiograph
should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as re-orienting or relocating the PageWriter TC cardiograph.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
